Videos: Inside Louisville's Mega Cavern undergroud bike park
Disused quarry now home to 320,000 square feet of MTB trails and BMX tracks
A disused mine in Louisville, Kentucky is now home to a spectacular bike park including BMX jumps and singletrack runs – all of it 100 feet underground. The Mega Underground Bike Park covers 320,000 square feet, and opens next month.
Opened in 1930 as the Louisville Crushed Stone Mine, limestone was quarried there until 1972. In 1989, Jim Lowry and his business partner bought the quarry and turned it into a high-security commercial storage facility, which continues to occupy part of the complex.
